Ok lets do some more knife talk! This is one of my favorite subjects and it is about combinations and Scandinavian edge.
blade on the Casström is almost 4mm thick (3,8mm) with a Scandinavian edge. This I have learned is the best edge for fixed blade knives and it makes the tip section very strong.
Having two blades can be valuable to have and the blade used on the Wenger new Ranger is large enough to be an outdoors blade for absolute everything by itself. The combination wood saw and blade is incredible. A fixed blade knife that can do some
harder tasks and or be clean all the time is of valuable help. I would hesitate to not having two large blades. The New Ranger Blade got one hand opening and locking mechanisms. This construction has been tested well. I have used it as a safety knife in my kayak on the life-vest belt in a pouch. In my experience I learned that this was actually safer than a fixed blade. I will explain why. The Wenger New Ranger was easily reachable from the pouch, it could be opened
with one hand and it was easy to release the blade in again. A sheath knife is too long and clumsy. The Ranger blade and the fixed blades I used was about the same blade
length. It was not easy to reach it on the side and to put it back in the sheath again. I learned that in a kayak fishing the Wenger knife beat anything else. The slim blade is very useful. I do not like to carry a sheath knife around the neck in a kayak.
It is difficult to see and I do not want to cut myself. Folding knives with OH and locking mechanism is perfect there.
Casström has left the edges on the back of the blade sharp for fire steel. Every part of the handle is fit perfect and rounded like I said earlier. The only thing that could be negative is the lanyard hole that is a bit sharp.
This could cut the cords in time. This can easily be rounded oneself. A lanyard must be present around water all the time! Write it in stone folks.
There are some that wonder how oiled masur birch and leather takes saltwater environments? The answer to this is easy and if you follow maintenance guides by the makers it will last a very long time. I noticed that hunters that dress animals have
sheath knives with wood and leather that lasts a long time. Traditional materials stand the tests of time.
I have a small challenge to you as well. Will O2 steel develop the same patina as
regular carbon steel? I would like to know. Cr or Chrome is one of the elements used in stainless steel to achieve corrosion resistance. On K720 the Cr is low and it will rust without maintenance. It will tarnish as they say. Let me know!
The Casström number 10 Swedish forest knife have a total weight 252 grams and knife alone is 183 grams.
By using the new Ranger knife in my kayak as a safety knife I discovered that it was perfect for safety and I started using it on the fish when inside to kill it. This was the fastest
and safest way for me without a doubt. It must have been a funny view for the people that could see me when I started fishing from fishing kayak some years ago. It was not easy at first but a lovely feeling when
I started to master it.
I hunt and study Polypores and some of them are hard as wood. A good fixed blade and the Wenger saw works perfectly in combination. The slim Wenger blade cuts
with high precision.
I will explain some about my thoughts and forgive me if i write strange or difficult. Ergonomics=comfort=safety. These are the three most important factors that complete the design.
I am a big fan of the Norwegian Tollekniv that is a traditional handle used here. It got a barrel shape almost or a small trout body section. This handle has taken all tests of time over 1000 years I like to believe. This handle
locks in the hand and can be used in any grip direction or position. It locks in the palm of the hand secure. This shape is actually so well developed that is can be polished with a fine surface without slipping. It is designed so well that even with blood
and remains from fish it is not slipping in the hand. The “tollekniv” handle is in other words a perfected one.
The Casström handle is very special and it is
on a full-tang construction. This handle got all the factors involved. I cannot see that this design hurting the three most important factors. It is comfortable in many positions and it locks. It is very comfortable. Nothing beats the tollekniv handle with
traditional design. But this full tang handle design is very intelligent and well done for a full tang knife. It brought further knowledge for me. I am not completely sure who is the designer yet and from what country?
I have seen some looking similar before but not completely.
This handle is complete and I cannot find any negative in this design. The lanyard hole
I mentioned is no problem for the hand.
I would also like if you would take the time to see what I have written about rescue knives and ergonomic on sakhome.com.
To complete the talk today i will mention some about the Scandinavian edge. In my opinion the true Scandinavian edge is with one angle. It should be completely
flat at the complete edge section. As said before you can find information and tests on the steel and edge on the internet. On my knife it is flat and that is Scandinavian edge to me. I noticed on the webpage that the words written in Swedish suggested
a convex edge. This is sometimes mentioned as Scandinavian edge too. On the webpage on English it says flat Scandinavian edge. On my knife it is flat with no secondary edge either. Remember that when you sharpen a flat Scandinavian edge this got some advantages.
That said it depends on how you sharpen the knife to be able to continue this flat edge. It will always be a small section of the very sharpest part of the edge that is not fully flat and it will in some cases look like micro secondary edge. A small sharpening
stone will in most cases make a convex edge in time no matter what. Many say that such sharpening is only maintenance and correct sharpening must be done on a machine. In some sense this is correct. If you use large sharpening stones you will be able to maintain
the flat edge longer.
I can add some that on the
webpage in swedish it says “konisk” it means conical and that is usually without convex. It is so that when konisk is mentioned people may hesitate. That said people misunderstand this. There is always
a micro secondary edge on a flat Scandinavian edge because the last part of the sharpening involves a sharper angle. This we do when sharpening by hand as well. That said I can mention that this last part of the sharpening can be done my machines in a factory
and the micro part may have a more micro convex line. Sharpening by hand is demanding for any grind or edge geometry. The angle and results…..
I can see that the Swedish forest knife is available with a full flat grind blade too. This is a completely different grind and edge. It is not as strong but it will cut more precise and cut better in some materials. It any case it is a weaker blade
and edge. It will be sharper. The Scandinavian edge is the best and it will be a sturdy blade for bushcraft. It got lots of material behind the edge that is good.
